摘要： Banana is considered climacteric fruit that undergoes rapid post-harvest senescence, making it highly susceptible to diseases such as anthracnose, leading to a decline in quality. To address this issue, researchers investigated the effects of phenyllactic acid (PLA), a novel natural bio-preservative with broad-spectrum antibacterial properties, on banana fruit after harvesting. The study revealed that PLA treatment resulted in improved attributes of postharvest quality, including reduced changes in peel color, soluble solids concentration, and firmness. Additionally, respiratory rate, ethylene release, and disease index were significantly decreased, indicating that the fruit's physiological processes were better regulated. Furthermore, PLA treatment enhanced the activity of disease-resistant enzymes beta-1,3-glucanase and chitinase, and upregulated the expression of pathogenesis-related genes. Importantly, PLA demonstrated its efficacy in suppressing the growth of anthracnose-causing fungi (Colletotrichum musae) and reducing disease severity on harvested fruit. In conclusion, PLA treatment shows promise as a new approach to maintain the freshness and quality of harvested banana fruit by reducing disease development, regulating physiological processes, and enhancing disease resistance mechanisms.
